Enable multiple workflow for single form

Hi Team,

I came across a requirement where i need to create vendor approval workflow. whenever new vendor will create in system it should set the onhold status to all so that this vendor can not be used for transaction. after approval process onhold status set to be no. I have implement the same and this workflow is working fine for vendor on hold form(vendTableListPage). but when i check property for All vendor(vendTable) form the workflow related properties were already set with standard workflow(vendTableChangePraposalWorkflow).

is there any option by using that i can enable my custom workflow type for vendTable form.

any suggession would be appreciated and helpful.
