GDL Scripting to add new table leg option

[Sabrina]

Hi!
I tried looking into GDL scripting to add an option to have a column table base in the "Office Table 27". Unfortunately the whole idea of GDL scripting goes way over my head and I can't find any helpful tutorials online.

I really like using the Office Table as a regular table as it gives you so many different options in terms of table top shapes and edge profiles. However I sometimes need to use tables with a column base (screenshot attached). I have created a gsm object that looks like the screenshot attached, however it is not editable for when the size, height or tabletop shape change

Anyone know how I can change the script to include this table leg style?

TIA
