In Notion, my composition changes time signature from 2/2 to 6/8. I want the dotted crotchet of the 6/8 section to be the same tempo as the previous minim (half) note pulse from the 2/2 section. How can I get Notion to write the tempo as "new dotted crotchet = previous minim"? Ideally I would like to not have to write an explicit numeric tempo, as that doesn't convey the relationship between the section tempos in a way that is easily recognisable at a glance.
