I want a brand new field in Marketo named Lead Owner Queue that gives the name of the Lead Queue that owns the Salesforce lead. For Contacts and User owned leads this value would be blank.
Justification: we sync every lead to Salesforce. Most of our leads bubble up through a series of territory and status based Lead Queues. Our generic lead queue is called Marketing. It is very frustrating that I can't do an "If Lead Owner Queue is 'Marketing' Then..." In a lot of cases just doing "If Lead Owner Queue is not empty" would be incredibly useful too.
There is a related idea over here: http://community.marketo.com/MarketoIdeaDetail?id=08750000000HDlJAAW
I believe my proposal is very focused and acheivable and avoids the contention discussed in the comments of that idea regarding reusing one of the existing lead owner fields for this purpose.
