Ability to add multiple values at once in PX filters

Post on behalf of a couple of customers: 

Currently when trying to add values in the filters in PX we can add only one value at once and there is no option to either upload a file containing values to be added.

It would be very useful and makes life easy if we have an option to upload/add multiple values in filters in one go instead of adding manually each value.

Use case: If I have to add hundreds of account/user id in the account/user filter, currently I have to type all those hundreds of id’s, it would be great to have option to make it simpler.
