Ability to add a specific item in the <Map> block

[slesaad]

Description

For the EMIT plume data, I want to add a single plume in a map block for the use case 3 data story (draft here). But we can't yet do that, we can only specify the dateTime and it'll show all the available plumes as markers.

Correct me if I am wrong, but it is possible to specify a specific default location as well as timestamp, right @slesaad ?

Can you explain more the reason to only include one specific plume?

I guess this is the story we are talking about: https://earth.gov/ghgcenter/stories/discovering-large-methane-emissions

which also has maps of a single plume, like this one:

But it is currently not our own data rendered but a screenshot from another app.
