No RTC link inside the workitem & Workitem lock/dependency management

Good evening everyone.
Sorry for a couple of questions but I'm going crazy.
1) I know that it is possible to insert links inside the ticket and they are "summarized" in the quick information as dimensions (#1, #2, etc). The link I'm talking about is inserted in the description field, but the Workitem recognizes that it is a link and treats it as a dimension. I would like to know if on the client API side, configuration or whatever it is possible to manage these links without the mention or better to report them visually instead of with #1 with another identifier, even custom but not like this.
2) I followed Ralph's instructions to manage the related links between tickets, including dependencies or blocks, but they do not block me or depend on the workitems. What I would like to achieve is that if a workitem is blocked by another, before doing anything on that Workitem I would like to have to "solve" the other and I can't find how to configure this, even on the configuration side it's fine, not necessarily on the api side, just that once assigned I don't know the block, who blocks that one must be solved, worked on or whatever, before the other.
Thanks a lot to everyone, in advance and sorry for the questions.

The Quick Information summarizes the dependencies and that is thew reason why you can not see the details unless you hover over.
There is no customization that I would be aware of, that would allow you to do so. There is few link based behavior implemented in EWM and it is also not possible to have any preconditions or follow actions for some link types. I do not understand all details, but you will likely have to live with what EWM can do.

Thanks Ralph. I just tried passing a link as an attribute value, but it was not reported as a mention unlike the same url present in the description and discussion.
So I deduce that mentions are reported only if present in these two? In the attributes no? Do you know anything about it?
As for blocks and dependencies, I was convinced that there were some managements that could be set, but maybe I remember wrong.
In the meantime, thanks again.
