Can JotForm Do: individual users' sequential information on repeat form visit

We are interested in running a fundraising activity that would require supporting the following:

Individual people register

On those individuals' return, they log activity (it will be a number)

Ideally, each time they log their number, they will see the sum of the new data and their prior logged data. So, something like: Today you logged: 6 -- that brings your total to 10!

EITHER using the data submitted, move a pin on a map OR export the new total to another widget that can do this.

I know that JotForm can do parts of this, and I know it's able to do a LOT that I haven't used, myself. But, I'd rather not spend hours poking around looking for capability that isn't there.

Thanks!!

I do not think this may be possible to achieve since JotForm does not offer the ability to track submissions per person, you may indeed create reports based on the information submitted in some fields, but I do not think they may be so customized as you need.
