The only way to do that would be for you to write a custom function using the API

Thank you Ajay

Is there an easy way to implement this code into the plugin? Could I just copy it somewhere?
Sorry for this questions but I’m fairly new to writing functions

Not an easy way. This would go wherever you wanted to display this e.g. in the single.php. You’d also need to customise the loop to wrap everything in the a tag..
