Workflow rule only allows 10 workflow per module

Workflow rule only allows 10 workflow per module

Apparently a Zoho professional edition only allows 10 workflow rules per module. This makes workflow allocation literally impossible while allocating potential to different members of the team. I have 15 licenses.

Is there a way in which related alerts can be varied? In other words, is it possible to have different related alerts be triggered with different rule criteria. so if I say, if potential is 'x' then trigger related alert 'x' and if potential is 'y' then trigger related alert 'y'

Thanks,

Sumeet
