Is it possible to copy one 'Approval Groups' into another ?

Hello,

Say we have approval group A with amount limit 100,000 and account range encompassing 50 specific cost centers.

Now, I want to create approval group B with the same cost centers but a different amount limit of 150,000

The simple way to do is to copy A into B and then just change the amount limit from 100k to 200k. It saves the time to key in all the cost center range.

Now is there a way to copy a approval group ?

I have to this for 500 positions. so its a big piece of work.

Regards,

Ingrid
