Link DashTable cell to download link

Hello,

I have a table of summary data and I would like to be able to click on a given cell in that data and link to a generated csv of that relevant subset of the data. For example if one cell shows the number of overdue jobs i would like to be able to click that, generate a list of those jobs (just subset the data) from my global df and export to csv and download.

A cursory google shows adding this functionality may have stalled, is this correct and/or is there a decent workaround?

Thanks!

EDIT: Now that i think about it, might a better way be to encapsulate each app in a class and make a new instance for each user? Do call backs work from within objects?
