Hi Sushant,
I think this is not possible if you are not using scripts too. In fact if you use scripts, you do not need SAP-PI also (to transfer files). Scripts are enough to meet all your requirements here. If you want to manage this through PI , bring in a mapping in your scenario and generate different filename,target directory name using ASMA or variaable substitution.
Then one receiver agreement is enough.
