URL in email notifications with External Unique ID instead of ROW ID?

Hi guys,

We send out email notification via workflows to users when certain events are occuring or stages are reached. The email has a link to the CRM record detail page.

This is the URL I use and I pass the Account Id and the TAG for the parameter.

https://secure-XXXXXXX.crmondemand.com/OnDemand/user/AccountDetail?OMTGT=AccountDetailForm&OMTHD=AccountDetailNav&AccountDetailForm.Id=%%%[<AccountId>]%%%

My question is whether you can create a similar URL by passing the External Unique ID instead of the Row ID?

If so, what would  "AccountDetailForm.Id" be replaced by?  is there a similar tag for passing External Unique ID?
