Hi @Shanmukh
I have not had a chance to work on SAAS connector yet but I did saw in below demo that during the aggregation we return the accounts as a List. You can go through the video and then there i think it should be possible to build custom filter method where you pass the list of accounts retrieved then filter out the required one. You can check the implementation of getAllAccounts method and there you need to apply some own logic to filter out the accounts which are not needed for you.
I hope this will help you. Please keep me posted but soon I will also be starting to build it on my own demo tenant and then i can try to implement this particular requirement and let you know.
Regards
Vikas.
