Sweep Parameter step causes testplan to show as unsaved

If I use a ‘Sweep Parameter’ step, after the test run, the tesplan will always indicated is is modifed and unsaved.
Is there any way to avoid this?

I can understand why it happens since it is modifying a child step parameter, but is there any way to have the parameter value revert to its original saved state after the test run?

Thanks,
