Here, ${\\sf T}$ denotes the trace of energy-momentum tensor ({\\sf EMT}) of matter fluids. The usual method (as discussed in the literature) is to choose an $h({\\sf T})$ function and then solve for the resulted Friedman equations. Nevertheless, our aim here is, without loss of generality, to reformulate a particular class of $f({\\sf R},{\\sf T})$ gravity models in which the Einstein-Hilbert action is promoted by an arbitrary function of the trace of {\\sf EMT}.
