[NTG-context] single spaced list items within a double spaced document

To whom it may concern, I need to have multiline entries in lists (e.g., Tables of Contents, Lists of Figures etc.) that are single spaced within a document that is double spaced. I have tried using \setupinterlinespacing commands as arguments to the attributes textstyle or textcommand of \setuplist. This does not work, probably for obvious reasons. So, I'm wondering if anyone has encountered this problem, or knows of a simple solution. Thank you in advance. Andrew
