How to remove proxy.pathsuffix pattern "/*/APIName" from custom report

[chawkimatta]

I have an API with the following flow condition:

<Condition>proxy.pathsuffix MatchesPath "/*/permit" and request.verb = "POST"</Condition> 

then a custom report is created using custom and common dimensions,
Common dimension used is proxy.pathsuffix:

when checking the report i am getting the same API many times due to the condition pattern "/*/permit"

property	sum(message_count)
/Sddln9NHAvBdiiFo8A9n0hPL104yBDDWgfPOtq/permit	2
/9JpwGd6Q3rZT4Jvk9JvoqIYVKGbL104yBDDWgfPOtq/permit	2
/EHTjr4Dt9coluFHw6wJfV/permit	2
/h4VOH4qox2dRKB1KUxWPaRMDbL104yBDDWgfPOtq/permit	2
/yQjMLxkGLVPyATmc7Rdy87g41/permit	1
/swVwkE1p43LxgfPOtq/permit	1

knowing that proxy.pathsuffix is a read-only variable we cannot change it dynamically, any idea how to solve this issue and group the API requests ?
