I think I am overlooking an easier way, but it is possible using regular expressions (regex):
Select your files/folders in Everything
menu:Edit => Advanced => Advanced Move to Folder
Enable Regex
Old format = ^(.*\\)(.*)$
New format = \1PARENT\\\2
Check results

Press the OK button.
Done
^ = marks the start of the filename (here including path)
\\ = a literal backslash
.*\\ = read as many characters possible until you find the last backslash
( ) = name the result \1
.* = read the remainder
$ = marks the end of the name (including path)
( ) = name the result \2
Resulting in (example):
\1 = Z:\test\test2\438\3154 [20219]\
\2 = test123456.txt

@therube:
the PARENT name is misleading here as it is actually about moving the files to a new subfolder (named PARENT ..)
You're right, also thanks for the help, doing it with regex helped me save a lot of time
