  We propose the extension of the position space approach to Feynman integrals
from the banana family to generic Feynman diagrams. Our approach is based on
getting rid of integration in position space and then writing differential
equations for the products of propagators defined for any graph. We employ the
so-called ''bananization'' to start with simple Feynman graphs and further
substituting each edge with a multiple one. We explain how the previously
developed theory of banana diagrams can be used to describe what happens to the
differential equations (Ward identities) on Feynman diagrams after this
transformation. Our approach works for generic enough (large enough) dimension
and masses. We expect that after Fourier transform our equations should be
related to the Picard-Fuchs equations. Therefore, we describe the challenges of
Fourier transform that arise in our approach.
