Have u tried taking away half the stuff she has in the play room. I find if my kids have too many toys out they can't find anything to play.
My 6year old plays lego, practices writing, likes pretend cooking, will pretend play hairdresser on me. I will introduce and semi supervise roll play- Dr and patient, dentist, shop keeper, farmer whatever.
Shop is easy cause they can draw stuff to sell and draw money etc. It can go all day with just swapping the customer and shop keeper around.
Moping and washing windows are favourits too

Sorry if it doesn't make sense, the barefoot princess is covering me with kisses
