I'm not happy with how Bridge auto stacks HDR looking for a script to..

Like the titles Bridges auto stacking is not what I need.

I want a script to look at the File name and  Exposure Bias to auto stack my raw files. Ie... take sequestual file names and stack based on the Exposure bias...

I Bridge my AE brackets sort this way

Photo1 Exposure bias equals +2

Photo2 Exposure bias equals -2

Photo3 Exposure bias equals 0

So I want a script that says...

If Photo3 Exposure bias is between Photo1 and Photo2 then stack.

Then open ACR and merge Photo (1,2 and 3). to create a Merged photo (PhotoMGD)

Then stack PhotoMGD with 1,2 and 3.

Then promote PhotoMGD to top of stack.

Then move on to the next Photos.

Is there anything like this availble to use? If not then how can I create it?

The Auto stack in Bridge uses photo time taken to auto merge and is often wrong.

Thanks.
