It would be excellent if we could not only use dynamic content for out of the box fields in Business Central but also to use any custom created fields.
As developers customizations are always being considered in various Microsoft products. It would be great if they can be accessed from all the products and applications on the Microsoft stack.
I have come into this idea from trying to have records create in Dyanmics 365 off the back of records being created in Business Central (very low effort data duplication). This would be be great for extending the relationship and integration between Dynamics 365 and Business Central.
