Hi, Jouke.

My apologies, i know that this will seem like a "broken record" with two responses being the same for two questions,

but unfortunately, for this one as well -

with our dynamic placeholders, so far we have not tried anything like this, 

so we can't confirm if or how it would be possible to add new/customized placeholders like that,

or to add code through an existing placeholder - our developers would need to add new functionality and examples.

-

As well as for the other ticket, you can make a development suggestion, and we ill do our best to add a valid solution for this as soon as possible.

Please feel free to search on our suggestions page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there,  and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like ( it is also available in the plugin dashboard), where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

-

If you have coding skills and wish to try to make a custom solution now,

you can check out our available hooks for Developers on this documentation and see if you can find any hook that might help.

Please be advised that custom solutions with hooks are not included in our support.

You can also research resources such as Stack Overflow to see if any other user perhaps found a workaround.

( We do like to give examples for certain solutions, but for this use-case, we, unfortunately, for this specific use-case, we don't have anything yet)
