This thread is old and you've probably moved on, but for anyone else looking for a way to fix this..
You can modify the symbols for start connection and end connection to have them look how you want. The default connections that come out of the box are Cantilever Moment and Moment Frame. you can search for either of those in the project browser and edit the symbol. save it as wall bearing or whatever you want and make the changes you need to display the end as you want it to look. Keep in mind that the connection symbol will be attached to the symbolic end of the beam. You'll need to add parameters to the symbol so that you can adjust the location of the symbol to be were you need it. left of the center line will be to the outside of the beam end, right will be toward the center of the beam. You'll need to adjust this to match the symbolic cutback distance plus your desired symbol requirements. the symbolic cutback distance can be found in the structural settings. The symbol will also need a line that matches the thickness of the beam to extend the end.
once you have the symbol modified and inserted into you project, go to the structural symbols portion of the structural settings and create a new connection type. assign the symbol you've created and then you'll be able to pick it as a start or end connection from the beam properties.
I've attached a 2018 symbol for reference. It's not a beam bearing but it adds a dot to the connection location. you can see how it works and go from there.
