can you switch the grids in your cache? (25832 before 3857)

However, when accessing the layer within the WMS in a projection not matching the grid projections, it seems mapproxy doesn’t choose the best grid as source for transformation. E.g. when requesting the layer in EPSG:25833 I would assume the best source is EPSG:25832. Mapproxy however seems to always use EPSG:3857 as source when a projection doesn’t match. Is there a way to influence the behavior of mapproxy for choosing the right source grid/projection depending on the requested srsname?
