IMPORT and REPLACE

Hi.

I think that Zoho Creator is a big step for all in building Great apllications. Bravo ! I would like to use it as a lead repository for my sales people and partners. (Channel Management)

I would love to have the possibility to have an IMPORT and REPLACE functionnality

This feature will help us
1/ "Export Data" in a spreadsheet,
2/ Mass change and Mass update these existing data,
3/ re-import my data and have them REPLACE the whole "old" record (perhaps we can do this if we provide the Record ID in the import Excell sheet...)

Anyone with the same needs ?
Is there a way to do so actually ?

Thanks and one more time BRAVO :-)
