Enhancement Location Selector - Multiple Options

[akaleMulder]

Add instructions on how to select multiple locations. Not everyone knows they should use Cmd+Mouse click to select multiple options.

Create a new landing page, scroll the page down.

It is probably a good idea to change the presentation of this field to a multi-select checkbox.

@akaleMulder this needs additional testing due to concerns around regressions for pages that rely on the single drop-down vs. the checkbox field. Could you provide additional insights for business requirements for this enhancement?

Story point estimate: 8.
