I may be misunderstanding, but to be sure I just wanted to share some text from Obsidian Help in case you may be confused about the option available to manually create the block id yourself as opposed to linking to the block via suggestions and having the block id generated by Obsidian. Anyways here are two quotes from the Obsidian Help section called Manual block IDs.
“If you want human readable block IDs, you can manually put ^your-id after a block. Make sure there’s at least one space if you’re putting the ID at end of a line.”
…
“After you add the block ID manually, when you refer to that block, your-id will be used instead of a randomly generated block ID.”
…
So you would be able to just paste or type that id if you wanted. Anyways, if you already knew this, no harm done. If not, I hope it helps. Good luck.
Thanks
