title: Selected / Marked records on Business Central page
body: <p>In an AL Extension CodeUnit, how do you iterate through the records that a user has selected / marked / ticked on a list page using the 'Select More' functionality? For instance, is there an IsMarked / IsSelected / IsTicked property in a data-type somewhere? Or, can you pass in the already drilled-down list to the codeunit?</p>
