Hi! Welcome back to the forum!
All charts that are possible to geographically reference should be able to show your position.
It is very common for taxi charts to contain elements that are not to scale, and in that case, it is no longer possible to show your position. This will not change, unfortunately.
In many cases, however, the map itself (not the charts) is really helpful in such scenarios! It contains lots of the same information, including taxi lines and holding points. Here is what it looks like for EGLL:
Perhaps that can be a good alternative for you as well?
Kind Regards,
