Hi Gilj,
This is possible although it won't push the changed URL in the delivery content itself but on clicking the link the customer will get directed to the new URL.
Here are the brief steps which needs to be performed.
1>. Get the primary key of the delivery in question and convert it to it's hex value. Example for primary key 110011 the hex value would be 1adbb
2>. Lookup the folder in the campaign installation directory \var\<instance_name>\redir\url\2018 and you would get an xml File with the hexadecimal ID of the delivery. so in our case there will be a file called 1adbb.xml
3>. Inside this file , all the URLs which are part of this delivery and which is being tracked will be present . You simply need to replace the url with the correct one and when someone clicks on the old link from the delivery , they will be redirected to the new URL you updated here
4>. Restart web and Apache to make sure redirection settings are updated.
