Looking for a additional feature as QTY PER METRE

Looking for a additional feature as QTY PER METRE

Hi Team,

In zoho invoice normally we are having feature which describes about qty, amount and so on... but am looking for a feature called qty/metre. For eg. in an item description it's about cable wire, there am looking for an option which gives laying of lan cables in per metre format. So my request is for replacing qty to qty/meter.

Kindly let me know how i can get that feature or if not if you people can develop and let me know.

Thanking in anticipation.


Regards,
Rajesh S
