SQL Optimizer - ask before deleting results from alternatives removed from current run

First: SQL Optimizer is an incredibly powerful tool once you have understood how to use it - which took me quiet some time ...

But with the current Version (9.2.3) when you want to rerun a subset of the alternatives chosen in "Test Run Different Bind Values" the data of the ones not selected is deleted.

This is very painful when you have the original running for over 30 minutes and therefor you don't want to rerun it but want to rerun some of the alternatives.

Please, ask whether data from alternatives not included in the new set should be discarded or kept.

If kept, just don't rerun but display them.

solved: modify alternatives and select explicitly which to run
