We have accounts in about 20 industry categories.
We'd like to have saved filters for each of those.
Why did Zoho institute this arbitrarily low limit on filters? Have you considered revisiting your decision?
(P.S. I don't know why Zoho insists in its documentation on calling these "advanced filters" when they're the only kind of filter on these views and are not named as such in the UI. It made looking for help documents one step harder than it needed to be.)
