Trips (Zoho Expenses) to Zoho Books

Trips (Zoho Expenses) to Zoho Books

Is there anyway, we can integrate the Trip Option - Zoho expenses  (with approval matrix) to a PO and later on map it into the respective invoice. 

Idea is

Trip (with approval matrix) -> integrate to Books through PO module -> Convert into Invoice -> and approve by Finance 

This will reduce the time
