According to this, you should be able to right click twice with a chamical tank containing a chemical and have the storage monitor display that chemical.

This does not work for me, using the following mods -

Forge 43.2.0
Applied Botanics 1.4.2
Applied Energistics 2 12.9.3
Applied Mekanistics 1.3.4
Architectury
Botania
Curios
Hammer Lib
JEI 11.6.0.1015
KubeJS 1902.6.0-build.142
KubeJS Mek 1902.1.4-build.11
Mekanism 10.3.8
Mek Generators 10.3.8
Mek Tools 10.3.8
Patchouli
Rhino

This also happens with Applied Botanics and mana tablets.
