How to create a multi line text in the elevation dimension?

[LeeJaeYoung]

Why didn't you create a multi line in the elevation dimension?

[DGSketcher]

Select the text in the dimension (not the dimension graphics) then rt-click and you should have an option in the context menu to edit the text as required.

I just need to be able to set SL: FL: etc in the elevation dimension and save it to favorites.
I don't quite understand your thoughts, but I'm just giving my opinion.

I can't save to favorite, which is the advantage of Archicad, so I work twice.

Ah~~~
Did you tell me how to edit it?
I guess I misunderstood because the translator translated it strangely. ^^

DGSketcher gave the method... but here are screenshots of the steps.  After placing the dimension, select the dimension text box (NOT the dimension itself!), right click, and select Dimension Text Settings....  You will see the multiline option there.
