It is. You can use scheduled report alerts for this and by using the report below. This should give you a notification when the amount of scanned installation are 31 or higher. Do note you will have to replace YourSoftware with the exact name given to MS Project in Lansweeper.
More information on how to create a report alert can be found here: https://www.lansweeper.com/kb/113/sending-email-alerts.html
Also note that if Lansweeper has not yet scanned the asset with the software, the count will not be accurate.
