CMS Widget: Trim post.title

[reteep]

I got this in a recent posts CMS Widget:

<a href="{vb:link thread, {vb:raw post}}">{vb:raw post.title}</a>


In the forumhome_lastpostby I found this:

<a href="{vb:link thread, {vb:raw threadinfo}, {vb:raw pageinfo_newpost}}" class="threadtitle" title="{vb:rawphrase go_first_unread_in_thread_x, {vb:raw lastpostinfo.lastthread}}">{vb:raw lastpostinfo.trimthread}</a>


I can't use that function in the CMS. So my questio is, is there any trim function I can use in a CMS widget?

Thanks!
