Textile markup for files

Hi,

I updated an older site of a client which uses a lot of embed files in textile formatted text blocks. I'm, struggling to figure out how to properly format the links with different text and title.

Until the update (v2.x), links to files locked like this:

"read":/perch/resources/dc-vortrag.pdf

After updating perch to v3.x, the links to files look like this:

[cms:asset 1720 title="title from file"] which create a link like this: <a href="file.pdf" title="title from file">title from file</a>

How would I format the links in textile to create a link that has the default title but a different text, like so: <a href="file.pdf" title="title from file">read this</a>

Thanks. Best
