Can we send combine task notification and custom alert for individual notification

Summary:

We have an offboarding Journey where we need to send a combine task notification to prevent separate notifications to the performer. At the same time we want to trigger custom alert notifications to users who do not have access to the system when specific task is completed by the performer.

Example: line manager gets a combine task notification and one of the task has a question if there is a parking badge. If the manager marks responds as Yes, custom alert should be sent to facilities to disable the badge.

Due to current product limitation the custom alert cannot be sent if combine task notification is enabled and viceversa. Anyway to achieve this?
