Yes and no.  You can't be fully dynamic but you can get close.

  <al-value name="expand_this" lookup="macro_table">

Then have a lookup table which looks like this:

  <al-lookup name="macro_table">
   <al-item expr="this">
    <al-expand name="this"/>
   </al-item>
   <al-item expr="that">
    <al-expand name="that"/>
   </al-item>
  </al-lookup>

To use this in your code you would just set ctx.locals.expand_this to
either 'this or 'that'.
