selection of production version based on least lead time through optimizer

Gurus,

We have a scenario where we need to select the production version (out of say 2 production versions) with least lead time during the optimization run. Please note that the production version with least lead time is not the default production version which is used in planned order while planning run.

Is it possible to select the production version with least lead time through optimization run?

Thanks in advance!
