Yeah something along those lines, though I don't really like the `(for SSPP_xxx)` suffix which we should either drop entirely and make the "heading" less of a "heading" ========================= SSPP xxx ======================= ... ------------------------- SSPP_CSC ----------------------- ... ------------------------- SSPP_QSEED --------------------- ... And/or inline the numbers: ========================= SSPP xxx ======================= ... ----------------------- SSPP_xxx_CSC --------------------- ... ---------------------- SSPP_xxx_QSEED -------------------- ... Either works, or any other pattern in the title (e.g `SSPP xxx: CSC`) that clearly tells the blocks and sub-blocks apart. - Marijn
