How to create conical reduced branches for spec driven piping?

Question

Hello everyone!
 
I'm searching for a way to use conical branches (see attached pic - it's a branch with different sizes for each outlet) in spec driven piping. Since the ASFILE offers "SIZE", "NSIZE" and "BSIZE" it should be somehow possible.
 
What I tried in the ASFILE (unsucessfully):
- Category: BRANCH and Code: BRANCH_REDUCING --> this seems not to work if there is a value for NSIZE
- Category: REDUCER and Code: INLINE_REDUCING --> the part can be selected in the "insert Fitting" dialogue, but the drop-down-list for "new size" remains empty (message: no Fitting Name from autoselect). Also tried to Combine BRANCH with INLINE_REDUCING and REDUCER with BRANCH_REDUCING, same result.

Any Ideas?

Sorry to be the bearer of bad news here, but sadly, I don't think this is possible.

Check out a similar question here:

Here's a support case on the issue: https://www.ptc.com/en/support/article/CS273955

Similarly... "schedule" is not used and can't vary for any of the ports either: https://www.ptc.com/en/support/article/CS3155

Hope this helps.
