How to access font versions in LO?

Why can’t we access all versions of a font in LO? When I go to select, for example, Futura, I only get Futura. Then I can only control that font using LO’s properties settings (i.e bold, italic, underline, strikethru, etc.). However, Futura has 6 unique, nuanced versions:

futura book
futura book italic
futura light bt
futura light
futura light italic
futura

How can I access those on LO 6.0.2.1?

LOL Never mind. I found the setting: the little greyed out box above the font size pop-up menu.
