Weblinks_filter: does it / can it do this ...

probably this has been asked and answered, but i didn't see in issue queue:

if i'm understanding how filter works, if i use [link: my link] inside content in a node, weblinks plugs in the URL saved at 'my link' and inserts the text 'my link' in the page content.

i'm looking to do something slightly different. i use the same link in multiple places in my site, but the link text needs to be different. i'm looking for way whereby i can easily update a single link in one place that gets propagated to all the instances where that link is used on the site.

to do this using weblinks_filter, i believe i would need to create #n separate links and insert them unique_name by unique_name into each location on my site. this doesn't save me any/much work.

i don't know how filters work, but the image i have in my head is a two-part filter where part 1 is the saved weblinks link_name and part 2 is the link_text i want to use in that instance. so, for instance, two instances using the same URL link might be: [link: link_name "This is the first instance"] and [link: link_name "...and here is the second instance"]

is this possible somehow?

thank you for your help.
