Import updating existing data : pb with "else" please !

Hi all,

I know that importing data today is just to create date, not update.
Will you (soon?) developp this feature ? I do need to import data matching for example on ZohoID or any another field (formula field witch concatenate several fields could be useful too).

We also should ba able import data into multiselect fields, where data are separated by , or ;

Waiting, can you propose us a script to do this please ?

Thanks Zcreator !
