Need to capture POW location at task level

Hi,

We have a requirement to capture Point of Work location (which is going to be an internal location) at task level. This is going to be a location where fulfillment takes place and is different from task owning organization's location.

Please share your thoughts on where can we capture this POW location at task level.

In task detail form there is a field named location, but I beileve that is to capture client site location so that may not sereve our purpose.

Thanks,

Mohit
