Scale Tool and User Input

[Jim]

Is it possible to use the Scale tool on a DC, and also allow user input for the same attribute?

Example:

This formula forces the Z length to a multiple of 6 when scaled with the Scale Tool.

LenZ: =largest(6, round(current("LenZ")/6)*6)

Now, can I also allow user input in the Component Options dialog without wiping-out the formula?
