Copy or duplicate a section/item of a block to reduce formatting task

I'm wondering if there has been any update to this, or if I can add a feature request (or three)? I create a table in one tab and i would really just like to copy it to another tab within the same block or in another block. A block template is great but you still have to go through the whole (tedious) process of creating and formatting the tables over and over.

I have found several times that I would just like to be able to duplicate an existing tab and modify it within the tabs section, including attachments. Or be able to create template tables and insert them into blocks already formatted (perhaps filled in too). 

being able to copy data from an excel table into the Rise table all at once rather than cell by cell would be nice, and if i could copy formatting (cell color, font color/bolding) that would save me a ton of time. recreating the tables rather than inserting images gives me the chance to type around them AND insert an image, but the manual process is killing me.
