Various studies analyze dinosaurs (including birds that they think evolved from dinosaurs).
And other studies analyze pterosaurs.
But no studies include both dinosaurs and pterosaurs scored on the same characteristics.
The one exception is the 2022 study which includes the analysis of one character - feather type, for both pterosaurs and dinosaurs.

See tab 4 of spreadsheet.
Notice that Tupandactylus is scored as feather type 5.
Consider the short tailed pterosaurs (eg. tupandactylus) and the short tailed scansoriopterygids (eg epidexipteryx).
If they were scored on the same characteristics we would see the
following:
Both have wing skin membranes, both have the 4th finger the longest, both have short bony tails and both have stage 5 feathers. (Along with other characteristics they share).
Both have wing skin membranes, both have the 4th finger the longest, both have short bony tails and both have stage 5 feathers. (Along with other characteristics they share).
It could certainly change the cladogram if the pterosaurs and the
dinosaurs were scored on the same characteristics.
