Hi and welcome to the Community,
A nice first post for a question that has been eluded in a previous request and for which I’d also like to understand why we can apparently not achieve this (without breaking it down in multiple DT).
I tried my workaround with a variety of approaches but no, just couldn’t do it.
The most obvious method (\n + “”) works fine for the GUI but is not accounted for a dynamicTexture. Wonder why this is.
Hopefully @labris or @Evgeni_Popov will have some insight on this. Shouldn’t be too long 
Meanwhile, again welcome to our Community and have a great day
