It sounds like you are probably coming from using spreadsheets where you had a new sheet/tab for each client, no?
You may not want to hear this, but your layout sounds like a prime candidate for rethinking/reorganizing to best utilize the strengths of Airtable as a relational database.
Before I expand on that a little, I want to assure you that this can be done relatively painlessly, and I am willing to help with it, if you’d like (you can Private Message me for details).
My suggestion is that you have a single table for Clients - this stores each client you have as a record (a row) with all the pertinent data (address, contact info, etc).
Have another table for “Events” (whatever they are, whether projects, jobs, what have you). Have a linked record field in this table that links an “Event” to a “Client”. Make it so that you can only link 1 “Client” to each “Event” - an “Event” can have 1 “Client” , but 1 “Client” can have many “Events”. Now all of your “Events” (which presumably have deadlines) are on a single table, but linked to your “Clients” - you can now use the Calendar view Airtable provides to move your deadlines around.
