Yes. Although the documentation was only added
in version 2.23.3, the feature itself is much
older. Have a look at
https://lilypond.org/doc/v2.23/Documentation/notation/bars#measure-counts

Put the dynamics along with the repeat in a
simultaneous music construct << >>. Overall,
the passage might look like this:

\version "2.22.1"

\new Staff \with {
  \consists Measure_counter_engraver
}
<<
  \repeat percent 8 { f'4 r c' r }
  { \startMeasureCount s1*2\< s\> s\< s\> <>\! }
>>
