I've added a new multi-select field to an old form so that I can share one same report with different clients and each of them will only be able to see the records that are relevant to them. The multi-select field is called 'access' and basically it will have the zoho.login email of each user that can view that record, and then the report will have a filter using the zoho.login that will check who is accesing the form and show those records.

Since this form has existed long before I needed to add this filter, I'm now in need of updating all ~26,300 records at once, however there is a limitation of deluge statements that doesn't allow to do more than 10,000 on my premium account. What can I do?
