Inputs values, properties in presentation

Hello,

Anyone has ever tried to do a workflow with input values that the same value could be used over 30 workflows for different purpose, but still I'd like to control the input values.

So far we weren't controlling input values, but I'm trying to do that now, and I was thinking to use a Configuration Element to store my possible value for that input parameter. Is that possible ?

So far I haven't found out how to do that.

Thanks!
