Envoys of the Everqueen and Heed the Spirit-song

How are these supposed to work together? Do I get a 10" bubble around the Treelord Ancient and each unit of Hunters on the field or do I have to choose who gets the bubble when I use the ability? 

Heed the Spirit-song:

The Treelord Ancient speaks to its kin through the spirit-song, warning them of approaching dangers. Until your next hero phase, you can re-roll save rolls of 1 for Sylvaneth units if they are within 10" of the Treelord Ancient.

Envoys of the Everqueen:

If a friendly Sylvaneth Hero uses a command ability, you can measure the range of that command ability from a friendly Kurnoth Hunters unit instead of the Hero.

"Instead". So you can pick either the Treelord or a unit of Kurnoth Hunters as the centre of the (single) bubble.

I would play it as the bubble only extends around the tree Lord because the ability specifically states the tree Lord but I can see the argument the other way. If it hasn’t been faq’d try asking on the FB page.

This was the answer in the Sylvaneth thread as well. I'm going to play it this way until there's clarification.
