How do you manage A+ content for multiple listings & languages

We are in the European market and have many marketplaces to manage. Each marketplace has their own Amazon ‘account’ and language and thus A+ content.

For us it is quite some work to manage all the uploads, texts, refreshing data, updating A+ content blocks etc. for each language/marketplace. Is there an app/service that can handle this? They do have an API, so it should be possible. Or should we create our own app?
