Is it possible to customize and show discount % for line items in quotation?

We have quotations which need to show discount and tax % on each line item. Currently, we customized it to show only disocunt and tax amount. Is it possible to show %ages instead. This is a blocking item for our organization and cant use the s/w without this ability. Is there an easy way to get this customized?

Thanks,
Shyam
