Lack of option to change Backup Credentials in Acronis 2015 proves problematic

We recently upgraded to Acronis 2015, taking advantage of the end of year sale to keep our backup program current.

Unfortunately, there is now no way to change the credentials Acronis uses to log in and process a backup. We have 4 users connecting to a machine running Windows 7 Ultimate. Each User's backup was set up with Administrator credentials, and backups occur nightly. There is also an SQL Database running on the same machine, which each user connects to with a unique Domain Username.

Although Windows 7 Ultimate supposedly allows up to 20 simultaneous user connections, it apparently does not log off individual Administrator logins. What this means is, over the period of a week with nightly backups, the number of User Sessions exceeds 20 rapidly. We have had to end each User Sessions through Computer Management, and edit each user's backup to reconnect it to the remote storage machine.

This is a problem. Acronis should include the ability to edit User Credentials within the application to avoid this sort of issue.

The solution for now:
Deleting the TERMSRV/ in Credential Manager, reopening Acronis and editing the backup forces a prompt to change User Credentials for some of the users. For others, the same process, plus restarting the machine was necessary.

I can't imagine we are the only Acronis users experiencing this so far.
