How to make the combination technique that includes dynamic markers effective?

I have created some combination techniques in expression mapping, such as “legato+non vibrato+p” to map different sampled sound sources (different intensities have differences in cc3 switching), but Dorico seems unable to recognize such combinations in actual music score input.

Why is this? Is there any way to make it recognize? Or is there a way to replace it? I need different dynamic layers to load different mapping samples.

I tried it and e.g. marcato+sfz works to switch from marcato to another specific samples set using the given key switch combination but if I use the same key switches with p or f instead sfz nothing happens i.e. Dorico uses the marcato articulation.

Have you tried creating user added playback technique for each of the above mentioned combinations and hide the articulation?
