Include before and after php in module

Simple but efective, I would like to have new fields in the module:

Include php before module;
Include php after module;
Include php for each standard item;
Include php for each featured item;

The vlue would be some php file in the module temapltes.

Usually to customize the modules we duplicate the templates, etc. I would like to improve the news temaplte without changing it and also respecting flexicontent updates. The simples way to do this, I think. is to add in the module the possiblite to include other php files. I suggest does positions.

for example, if I want run a php script before the module:
I add a folder in the tmpl of the module called:
/customscripts/runbefore.php
In the module I would add to the fields:
Include php before module = "runbefore";

This way I can keep upgrading my flexicontent sites without problems. Does postions are usually what we use. I think this is simple but we wanted in the core

Thanks

This was added to the CORE fields helper class:

Ability to have a parameter with Custom HTML with replacements, including:
- field replacements (of current item of the item list)
- language string replacements
- current item's property replacements

this already used to enhance:
- field related items
- field related items backlinks

and it can be integrated with a little work to:
-- universal module as an alternative to field list
-- search view item listing (still thinking if this view should have an search view layout in templates management)

-- What you suggest make sense, but thinking maybe instead of executing a custom PHP file, to use instead this new replacement parameter in more than one places

For example I have a custom php file called:
"something.php" and I want to call it when the module is loaded how can I do this wihtout changing the news.php file?
