You can launch Trackster (the Galaxy native "Visualization") directly from one dataset, then add in any other dataset from any of your histories or from Shared Libraries.
Or, you can start the Visualization directly without any datasets, and later add datasets in all at once, or in increments. Make sure to "save" if you decide to navigate away while it is indexing (if the datasets are very large/numerous).
Other display options appear within expanded dataset as lines like "display in IGB Local Web". You can click on multiple datasets and they should all load into the same session at the remote host.
As noted in the Biostar post, datasets can also just be added to many external vis tools. But the above are the ones integrated.
Hopefully this helps,
