**Background:** There are several known lifts from integral weight modular forms to Siegel forms of genus 2, among them the Saito-Kurokawa lift. Another lift construction that is important for applications combines the Maass lift, which maps Jacobi forms to Siegel forms, with a lift of Skoruppa, which maps forms of integral weight $w$ with respect to ${\rm SL}(2,{\mathbb Z})$ to Jacobi forms of weight $(w-2)$. An example of this construction is the lift of the weight 12 form $\Delta(\tau) = \eta(\tau)^{24}$ to the Igusa form of weight 10. Thinking about motives in the context of Siegel forms of genus 2 leads to the following two questions.

**Question 1:** Has the lift construction by Maass and Skoruppa been generalized in a systematic way to congruence subgroups, for example $\Gamma_0(N)$?

**Question 2:** Is there a motivic interpretation of this lift by Maass and Skoruppa?

(Some references: the work of Skoruppa is in his 1992 paper (Math. of Comp. 58); a partial generalization of Skoruppa's lift to congruence subgroups has been considered by Gritsenko and collaborators in several papers. The Maass lift has been extended to restricted levels $N>1$ by Manickam-Ramakrishnan-Vasudevan in a 1993 paper (manuscripta math. 81). Question 1 is asking whether more systematic extensions are known.)
