We don’t consider the current behaviour correct (i.e. when you copy and paste material and there are dynamics at the same position in the destination passage as in the material to be pasted, the dynamics in the destination should be overwritten), but for various boring technical reasons this is currently not the way things work.
There’s no way to make dynamics at the same position go side-by-side beyond the automatic behaviour Dorico provides for immediate dynamics followed by gradual dynamics or vice versa, nor do we plan to add any.

So currently, it seems the favored way of entering expression text (espressivo, dolce, etc.) is by entering a dynamic+text and then hiding it. Are there any plans to add a specific expression text tool, like the Technique text popover? Otherwise, if we continue to use dynamic+text as a workaround for expression text, there will definitely be reasons to stack dynamics objects on the same rhythmic position. (Not to mention, when you turn off showing the dynamic in the score, it doesn’t turn it off by default in the parts, which is very unintuitive.)
