Report Duration of Timeline Activities with Filters

Hey Gainsters! Hopefully ya'll can help me out here.

We would like to see the amount of time CSMs have spent on specific activities for our clients. I've created a report for Timeline activities that displays the sum of duration for 3 activities. (See first screenshot)

I plan on putting this report on a Dashboard for the CSMs, CSM managers, and executives to view. However, I've ran into some problems.

• We want to see just the accounts that have gone through our Implementation onboarding process. However, the fields that specify if they're in Implementation is not in the MDA.
• We also want to see accounts that are currently in the Implementation process and/or see clients that have completed the Implementation process. The fields that specify the start and end dates of implementation are not on the MDA.
• We'd also like CSM Managers to filter it to view accounts that their CSMs are assigned to

The bottom line - the fields we need to filter the report aren't on the MDA. If there's no filter it just looks like screenshot 2 below. :(

Is there a way to do a Bionic rule and merge data AND still have all the timeline activities to report on??.....
