Problems with indentations

Very often I have to use different indentations in LO Writer which I found very difficult to use and time consuming. So, what I want to do is the following:

1.  Text, text, text, text,
    text, text, text, text,
    R1  text, text, text, text,
        text, text, text, text,
    R2  text, text, text, text,
        text, text, text, text,
        - C1 text, text, text, text,
          text, text, text, text,
            . A1  text, text, text, text,
              text, text, text, text,
              text, text, text, text,
        - C2 text, text, text, text,
          text, text, text, text,
            . A2  text, text, text, text,
              text, text, text, text,
              text, text, text, text.
              
2.  Text, text, text, text,
    text, text, text, text,
    R3  text, text, text, text,
        text, text, text, text,
    R4  text, text, text, text,
        text, text, text, text,
        - C3 text, text, text, text,
          text, text, text, text,
            . A3  text, text, text, text,
              text, text, text, text,
              text, text, text, text,
        - C4 text, text, text, text,
          text, text, text, text,
            . A4  text, text, text, text,
              text, text, text, text,
              text, text, text, text.

The text in all levels should be aligned with the right margin.
Using Linux, LO 7.4.1.2, save as .odt.
Any help would be appreciated.

Please edit your question (don’t use a comment or, worse, an answer, so that every detail is in a single location) to provide more information about your goal.

What you request looks like a multi-level numbered list. But it is not clear if numbering for R, C and A levels should be continuous across the “main” level.

  • If number is reset when you change upper levels, you have a standard Writer list
  • if number is continuous across levels, you have 4 intermixed independent levels
    This case is more complicated (for newbies) than the previous one and requires the use of list styles in addition to paragraph styles. In particular, you can’t achieve it with Format>Bullet & Numbering any way you try to configure it.

And don’t forget to mention, OS name, LO version and your preferred save format. Note that saving .doc(x) will not preserve the solution across sessions. Saving .odt is mandatory in your case.
