Design Library 18 x 14 SCH 20 Reducer

routing I don't see this in the design library anywhere and I'm wondering if there's downloadable content somewhere with a complete library of the piping needed.  Piping, elbows, 45°, go all the way up to 24" but the reducer library is limited to 12 x 10.  Is this intentional?

Is the work around to fix this to manually input all of the missing reducer dimensions into the configuration table?

If so is there a short video explaining that or just trial and error?

Appreciate any responses.
