Playing back a tied note into a repeat

How would I get this to playback properly in Dorico?

It’s not my score, but I assume the intention with the dashed line is to mean the minim is tied the first time, but when you repeat you should articulate the first semibreve.

Best I can seem to do is to make the first tie a slur instead, which doesn’t look right and doesn’t actually sound as it is supposed to either.

I can expand the repeats out (is there an easy way to do that in Dorico?), but ideally I would like to keep the score the same.

Thanks for any help.

Put the C before the repeat into another voice.


The second note in the tie sounds now, but the first note is silent.

I switched on voice colours so I could see that it was a different voice.
