Prompt for dimention value when adding TB part??

Hello all,

Wondering if it is possible to make it so when adding a TB part, the user will receive a prompt asking them for a value to input.  This value would then be used for the diameter of a pin.  With configured TB parts you can obviously select from a list of standard sizes (see below).  I would like to find a way to make it more flexible using custom inputs in one of the two places shown below.  Anyone know of a way to do this with TB?  Or without TB for that matter...

Thanks!
