Is there a way (or what is the best way) to include one of our custom mapped fields in JO in a report?

Specific situation: We have a quarterly report for our professional services team. We have the PSM mapped as a custom field in the program but want to be able to pull it into our final reports. I can access who the CURRENT PSM is via the relationship, but since this is used for performance we need to know who the PSM was at the time the survey was sent. There is quite a bit of turnover/moving accounts in this area of our business, so keeping track quarter to quarter is almost impossible.

BONUS if this was also available in the Analytics tab so we could show/filter by these custom fields there as well.
