Collecting values from custom parameters in Properties and Labels

[Thomas Nymann]

Custom Parameters can be called in Schedule. It would be nice if thi feature was available in Autotext fields, and in the Parameter list in the Property editor.

Now - I have created a parametric bicycle parking rack. This object automatically returns the value of parking spaces, this value can be added in a Schedule, but there´s no way to add this “custom” parameter in a Label textfield, or a Property that will read this value.

I was trying to achieve the same thing. 
I wanted to create a special property using the GDL parameters  gs_handle_type of door. And then use it for door maker. 
Search for a while but no. Strange that it's so easy with schedules but only within this function.
