Can I create multiple labels on same page?

I have created labels database and successfully connected it to writer (new → labels).
Now I can either print labels so that each page contains labels coming from one database entry.

Is it possible to print custom amount of labels per page?
For example I have 12 labels per page and I want first 3 to be entry “a”, next 4 to be “b” and remaining 5 to be “c”.

My current solution is to salve labels file and then manually copy “b” and “c” entries to part of “a” labels. Is there better way of doing this?
