Similar to being able to disable validation before performing a data deployment it would be very useful if there was an option to automatically uncheck the "Restrict picklist to the values defined in the value set" option for some or all of the picklist fields in a deployment.

We have data that includes picklist values that are no longer active this causes errors on individual records as part of the load. Currently I have to pick through all the errors manually then uncheck the option for the corresponding picklists fields on the target org. Then after performing the deployment I have to go back and restrict the values again - this takes a lot of time!
