How to sort columns in a table for linked models in SAP Analytics Cloud (SAC)?

Hi all,

we are working in the Import Mode on SAP Analytics Cloud and we have created a story based on two models linked together. The attached screenshots shows the table of the story, which is composed by the selected KPI from the two differents models, and the disabled sort option. We have created also a "cross" KPI between the models. Our issue is to sort the columns of the table in the way our client wants and this is not possible also without considering the "cross" KPI, but simply sortering the columns of the table.
