Looking for method of displaying float of a mid-project activity at the project level

Using P6 Professional version 24.

Is there a way to view the float of a constrained activity at the project level?

It is preferrable to see the -14 as the TF for this project, but since there are successors, it shows the TF as 0.

This number would be used to sort projects based on their criticality, so the float number (in this case -14) needs to be used for the sort. Since this screen depicts the activity level, a method is needed to transfer this figure (-14) to the project level where it would be used to sort the projects.
