To make Echosign remember data

When my customers fill in a document, there are fields that they populate very often. For example we have three form which needs signing and all the three forms ask for id documents.

Some cases customers do not type the same id correctly, resulting it more time to process them.

Can we make a feature or is there a feature where echosign remembers fields and when they were suppose to type again, by clicking the field echosign can auto populate them.

I know the current signature field works like that, can we make any other field similar to signature field?

Thanks
