Convert To Functionality For Custom Modules

I Have Created 2 Modules A and B from A module when click on convert to button all the fields from A module To B Module Populate with Subpanel Line Items in Edit View[Line Items Also Should Edit Before Record Save]. If I don't want any values to save i will remove the values and save the record. Is this possible.. If it is possible how can we do that ??
