Hide 1/1/0001 from Short Date in Workflow email

All

Using InfoPath and SharePoint 2010.

I've various date fields on my InfoPath form which can be left blank. These date fields are published to SP successfully as blank (to the human eye).

When I place the date field (short date) in a workflow created email, the date returns in the email as 1/1/1/0001 . This I understand is workflow default behaviour.

Can this value (1/1/0001 be hidden or replaced with a "blank".

I've 6 date fields in this email, any one of them could be blank. Is there an alternative to write multiple email combinations?

I'm trying to set a variable in place of a blank date fields yet all I get back is an alternative date 1/1/1900.

Thanks
