Data Plugin for other BUilder.io Spaces

Currently right now if you want to do data binding to say display a query of blog posts you can only connect to content within the current builder space OR use a data plugin for another CMS (e.g. contentful). We have a case where we have multiple sites and want to share content across sites (e.g. blog posts) so I need to query from one space to another. To do this I have had to create a custom data plugin that queries builder.io and uses plugin settings to configure the public api key of the other space. While this works it really should be a core feature of the product especially in regards to multi site support
