Adding Member Matching Expressions in bulk

hello - we are currently working to migrate from PCM to ePCM. We used the template to bring in all of our ruleset and rule configurations, but we do not see any option in the template to add member Matching Expressions.

For a quick background, our Entity dimension and Intercompany dimension hierarchies are the same. They use the same values, just provide different business purposes in the GL. This was allowed in PCM, but not allowed in ePCM. So, in ePCM, we added "IC_" prefix to all values in our Intercompany dimension.

Now, all of our rules' that use "Same as Source" Entity functionality for Intercompany dimension, we must use a member matching expression to ignore the prefix.
