Dynamic Routing Option

Is there a possibility to set the list of routing options of a task depending on a variable when starting a task?

I only found the "tally" method to set up events automatically but that does not seem to help in my use-case.

Use-Case:

Skip a routing option when a process/task variable has a specific value.

Pre-Condition / dependend variable:

                boolean ir_autocreated;

Routing in Task:

A

B

C

X

For Routing „X“ there shall be valid:

IF ir_autocreated == true THEN Routing Option “X” shall be "invisible" / not selectable in the task

Thank You in advance
