Customizing transmittal / submittal / RFI numbers

Does anyone know if there is a way to pull the company name (or a shortened version of the company name) from the package originator into the transmittal / submittal/RFI ID numbers as part of the prefix (i.e. pjt #-Company-0000001)?  Is there also a way to define how many leading 0s are added to the sequential number?

Thanks!
