How to pass through a date range to a dashboard from a table...based on cell value!

I am new to Grafana, but am coming up to speed as quickly as I can. I have searched for an answer to this problem but my be stymied by a lack of knowing the right terms to use.

I have a table based on a date histogram that counts documents that exceed a value for that 15m time slot. Works fine, gives results like:

15min Time Bin Count
2018-09-20 05:15:00 23.00
2018-09-20 06:00:00 16.00
2018-09-20 06:30:00 14.00
2018-09-20 05:30:00 12.00
2018-09-20 06:15:00 12.00
2018-09-20 07:15:00 8.00

What I would like to do is click on the timestamp and have it bring up a list of documents that match that specific time slot and only that time slot. (e.g. click on the first one above, get a list of the 23 documents that matched)

The query in the new panel is easy enough, but it is the time frame. I need to take that timestamp, create another timestamp 15min earlier and have that be the time frame for the new report.

This is (I am hoping) one of those simple things that my noobiness is causing me to not see clearly.

Anyone done something like this?
