Using appsheet with projects

My company has recently started using Smartsheet. We are a pool renovation company and each job is being set up as a separate project. We've been using appsheet for about 9 months now and want to incorporate our Smartsheet data. We want to have an app where our field workers are able to see each task assigned to them from the various projects and update on their status/add comments. However, I am not sure how to accomplish this without a lot of ongoing work - since each project would have to be added as an individual table to appsheet. We use Zapier for some other things but I’m not finding that to be anymore helpful as you have to select a specific table as well for any triggers.

Essentially, we’d like to leave them all as separate projects in Smartsheet, but need them to be in one sheet to be used for appsheet - while still being able to monitor all updates made in the field in the individual projects. 

Any ideas on how to accomplish this?
