duct accessory Size - how to show size only once

[HVAC-Novice]

I have dampers and other duct accessories. And the tag should show the size. but since the accessories have 2 sizes (air entering, air leaving) the oob "size" parameter in a tag shows me the size twice. For most (if not all) dampers and other devices the size will be the same in and out. At least I can't think of a fire damper, airflow station or anything else that would be a transition (e.g. entering size different from leaving size)

How can I make it to only show the size once? See below, i only want to show "24x16" instead of "24x16 - 24x16". 

Best idea so far is to create shared parameters that use width and Height of the duct and create labels from those. but I wonder if there is a better way? In the tag I can't format the "size" parameter. 

I'm having the same problem with Pipe accessories and there ended up using a separate shared parameter.

Hello,

The Size parameter normal behavior is to show all connector's sizes.

To avoid it, the only solution I use is a shared parameter.

Thanks for the response. That is what I feared.
