from what I've heard there isn't a way to set up the rules to dynamically change the HTML
Would I put the href tags in each website?You actually only need it on one -- Once a page(s) is an alternate for another page they're all considered alternates for each other,
This relationship is transitive — that is, if a document links to two other documents with the link type "alternate", then, in addition to implying that those documents are alternative representations of the first document, it is also implying that those two documents are alternative representations of each other.

If you have multiple language versions of a URL, each language page must identify all language versions, including itself. For example, if your site provides content in French, English, and Spanish, the Spanish version must include a rel="alternate" hreflang="x" link for itself in addition to links to the French and English versions. Similarly, the English and French versions must each include the same references to the French, English, and Spanish versions.

on the co.uk and .de, shouldn't those similar pages be referenced (canonical tag?) to the .com site?
