[O] C-c a e closes agenda buffer

[Gez]

I'm mostly working in a custom agenda view, refreshing with q or r,
but I like to frequently update my exported html agenda view (shared
in dropbox).  Each time I export with C-c a e the agenda buffer closes
and I have to call my custom agenda view again.  Would it be possible
to make it so that C-c a e aborts the refresh of the agenda buffer (as
if C-g were used after C-c a)?  Alternatively could a particular
custom agenda view be designated as a default to return to after C-c a
e?
