show tempo marking in exsisting piece

Hi,

suppose you have a score but you would want to show the tempo marking. how can this be done??
i know i can add a tempo marking but creates a new tempo which is not what i want. i would want the actual tempo to be shown.

currently i open the playback pallet and there i can see what tempo it uses for playback and than i go and add a tempo marking but i could imagine this can be done easier.

pls advice

greetings Martijn
