Show inlinks from baselined source modules

Initial situation:
We have two modules A and B, each containing an object a and b respectively. This is a simplified representation of the situation that exists in development. The two modules correspond to modules that are processed in different development cycles. The use of a baseline set that contains both modules A and B is thus excluded. This is because several baselines of module A may be created, and a baseline set should not necessarily contain the last of these baselines, but an older one.

Creation of the link:
A baseline 1.0 is created from module A. Object b is linked to object a [1.0], i.e. to the version in the baseline. From b it is possible to navigate to a[1.0], and from a[1.0] back to b. a in the current version has no link.
This corresponds to the expectation.

Baseline of the 2nd module:

Now a baseline 1.0 is created by Module B.

Expectation:

1. from b can be navigated to a[1.0], and from a[1.0] back to b.

2. from b[1.0] can be navigated to a[1.0], and from a[1.0] back to b[1.0].

Observation:

1. bilateral navigation between b and a[1.0] is possible, corresponds to the expectation

2. from b[1.0] it is possible to navigate to a[1.0], from a[1.0] there is - contrary to expectation - no way back to b[1.0]

Explanation:
The observation corresponds to the documented behaviour of DOORS. When creating a baseline, outgoing links become "one-way" links (half links), which are displayed with an empty triangle: it is still possible to navigate from this baseline to the target object (which may be in the baseline of another module), but not back from there.

Idea:
Since the information about which versions of objects are linked is apparently available in the tool, it is incomprehensible why this information is not used to be able to navigate back and forth between baselines. We see that this kind of navigation works in baseline sets. However, since already created (older) baselines cannot be included in a baseline set, we cannot use them in our situation. We need a comprehensible representation of why it was decided not to be able to navigate between baselines outside of baseline sets.
