Cancel approval or change approver

Cancel approval or change approver

Hi,

we are working with Zoho Desk tickets approvals. Recently we had a situation with a ticket where one agent was asked for approval. But this agent was wrong and we hadn't be able to change it or cancel the approval. We can find no way to do that. But, is there any way to do it with workflows or any other Zoho Desk feature?

We have a workaround using a bluprint transition to get out of the approval state and ask for another approval. But would be better if we can cancel an approval request or reasign the approver.

Thanks in advance, 
Regards
