Opportunity Close Date to a default 30 days from creation

Hello all,

We have a Customer requirement in our implementation where we need to set the Opportunity Closing Date to 30 days from the creation date. Currently the system sets it to a default of 180 days (6 months). Although this value can be overwritten in the Edit mode, wanted to know if there is anyway to set this to 30 days directly on creation of an Opportunity so it does not have to be overwritten. Could not find this setting/configuration anywhere in the system.

Thanks and best regards,

Nikhil
