How to set numerical values to the wizard blocks

Tunski

Currently using the ABB GoFa CRB15000 with Arc Welding. Through the use of Digital Output signals we have been able to send blocks of code into the Teach Pendant's Wizard. Certain signals are mapped out to certain blocks, so when a signal "doExample" is turned on then a Arc Linear Start block is added to the Wizard code. The signals are turned on and off through a Rapid Script. 
We want to however be able to have more control over the blocks, and be able to change its parameters too, so that means changing speed, job number, zone etc... It all depends on what the user wants to do, but we would like to have the option of changing these if user wants to. 
When these signals are turned on, however, they create the blocks with some default parameters or whatever parameters were used last for that block on the Wizard app. Somehow the wizard app remembers the last parameters that were used, so maybe those values could be changed or manipulated via Rapid code? Not sure how one would access those values though. Any ideas on how one could change those parameters, while still being able to use this combination of signals and Wizard app?
