Blueprint - Any way to delete process / Transition

Blueprint - Any way to delete process / Transition

Hello, 

First of all I think I'm going to really like the Blueprint feature, once I figure it out that is.  

I sure hope someone can help me figure out how to fix this.  

I created a blueprint for our account on-boarding and set up process - While I was testing it a large number of accounts were edited which made them enter the blueprint, ( I failed to put a criteria on this blueprint that limited entry to newly created records.)  Well, I realized that I made a few mistakes by adding certain fields in the during section.  For instance I put a series of check boxes in there, they should all be considered during the transition but possibly not checked, and one field is a date field that should be updated during that transition, the validation was that it should be today's date well these records older records have all been through the processes and I don't want to change the date to today,   It needs to stay what it currently is.  If I have to go through these records and update them then change them back to what they were - Well, there are more than 2500 account records and 3 transitions in this blueprint. It is pretty much a near impossible task.  

Please tell me that there any way to delete these transitions without having to take each record through each of the transitions that I put into the blueprint for new accounts.  

Guess I should have read more of the instructions or quit doing everything else for my job  while I was figuring out this new feature.  I just didn't realize I was going to create this mess in the new tab called "My Jobs",  Which by the way is a great idea , All approvals and transitions in one place, very cool unless the first time you look at it there are thousands of them.

Anyway Help please
