Update a parameter input when overridden in the definition

I have an input with 2 selectable values. In the definition, this will be auto-changed when the length of product entered is over a certain value.

So up to a certain length you can pick choice A or B, when over a set length the definition switches to choice B but the slider still shows choice A

Is there a way to auto switch the input parameter when product length dictates?

Manipulating inputs is not allowed, see this Forum post:

Also, similar problem was discussed below and it could work for your use case:

Thank you, i will pass this on to our developer.
