Create path alias to a custom link I have a taxonomy term that has its own template, inside that template, there is custom links that just add a new argument to the URL
for example the current path is /taxonomy/term/%, one of the custom links will send the user to /taxonomy/term/%/% 

with pathauto the url alias changes only when I visit /taxonomy/term/% (vocab_name/term_name), but it won't changed when I vist /taxonomy/term/%/%. I want it like that : vocab_name/term_name/%.

Is that possible ?
thanks in advance.
Check path_alias_xt and subpathauto, I have used subpathauto to achieve this for nodes and path_alias_xt documentation says it does for taxonomy terms too.
