Can you create a Link connector?
The idea is to have an option to use a Value listed for some features in Macro if needed, but since it is not practical to deal with a parameters list, I intend to add an Input connector via link and then to add a Value List Operator in Top Level of the Style so I can use it.
EG:
In Macro, I have the option to rotate some Geometry based on MatID, but since the Macro is supposed to be universal, my idea is to prepare an Arithmetic Expression eg: Input1*90;
Then, on the Top Level to add Value list:
1. 0
2. 1
3. 1
4. 0
5. 1
6. 1
7. .........
This will allow users to have a various range of control via Value List.
With this workflow, I could prepare some options in Macro, and if needed user can just add Value List Operator and have a lot of control.
