Can we use Piti as a meditation subject?

Can we use Piti as a meditation subject? There are 40 meditation objects are given in Visuddhimagga as follows. Ten recollections; ten foul objects; ten kasinas; four sublime abidings; four formless absorptions; one resolution into elements; and one perception of the filthiness of food. My question is whether we can keep four form absorptions as a meditation objects, but specifically Piti as a meditation object.
