Alias to a specific page withing a node?

Hello, I want to create an alias to the second page of a node.

When I post node/229&page=0%2C1 into the “existing system path” field, the path is displayed as node/229&page=0,1 after submitting the alias form. The resulting url alias does not resolve (goes to front page instead).

I tried being clever and submitted node/229&page=0%%32C1 which displays as node/229&page=0%2C1 in the alias list but it the resulting alias still doesn't resolve. (If the resulting alias is edited again, no change made, and then saved, it reverts to —> node/229&page=0,1. This isn't entirely unexpected, but it occurs to me that string handling could be made so repeated "saving" results in no such deterioration. I won't assert that said behavior is terribly important—unless one has a need for entering special strings... I digress.)

Is there a way to make an alias to a specific page within a node?
I'll recheck to make sure I didn't overlook any relevent post.
