Let \(A\) be a finite-dimensional algebra over an algebraically closed field. If \(A\) is an \(\mathscr{F}(\Delta)\)-finite quasi-hereditary algebra, then the endomorphism algebra of the direct sum of all non-isomorphic indecomposable \(\Delta\)-good modules over \(A\) is quasi-hereditary. Moreover,
