Alternate Repeat Markings

[gehentogo]

Hello everyone,

I'm using Lilypond 24.4 on Windows 11.

I really like the look of the manual repeats:

     \bar "[|:" and
     \bar ":|]"

How do I get repeats to look this way when using the default automatic
repeats? Such as:

     \repeat volta 2 {
        R1*4 }

Thank you,

Brian Eve
