Dosing kalk and mag

[The River]

In a small none demanding system I want to dose Kalk and a seperate dose of Mag. My question is can I mix the Mag with a trace element mixture that i formulate? Basically have a 2 part system kalk and Mag with all my trace elements mixed together.
Was wondering if its possible and if the chemicals will stay mixed after settling occurs?

Magnesium chloride and/or sulfate will be compatible with many trace elements, but the answer may depend on the forms of the various trace elements you elect to use. Do you have a list?

Just to be clear, the magnesium cannot be mixed into the limewater/kalkwasser, which I think you understand.

Thank you!
I am not educated enough to know which trace elements specifically. My plan was to add a predetermined product that claims to cover them all and then rely on ICP testing to confirm or deny I am on target.
May I ask, are there any specific trace elements I should not add to Magnesium?
