Can you target a lightwell?

when soloing on difficult fights I love it when a priest drops a lightwell and if they are real busy healing the tank you can grab some heals.

I'm not sure how much it will be needed but you could plant a lightwell at the feet of your dps before a boss fight and be able to have a macro to target the lightwell, click it then get back to dpsing.

May be useful in static fights perhaps.
