Better looking slashes and crosses in guitar tablature

Your idea

As in title

Problem to be solved

These are slashes in Guitar Pro:

And in MuseScore4:

The steps to make slashes and crosses in Guitar Pro is:

1. select a note or a chord, click slash in palette, then it becomes a big slash;
2. select a slash, click dead note in palette, then it becomes a big cross;
3. if clicking dead note when selecting note or chord instead of big slash, they will become small crosses instead.

Step 1 used to have bug in MU3 but fixed in MU4, tho the slashes don't look well in tablature, either version;
Step 2 is not achievable in MU3 or MU4. Trying to create a big cross in MU using the same step results in the picture above;
Step 3 is implemented in both MU3 and MU4, but the crosses looks weird in tablature. see also #11602 and #16500.

Edit

as what Marc has said, we can actually achieve the Guitar Pro style manually, tho its not perfect or efficient. See my comment below for a step by step instruction. If further discussion of the workaround is needed, please continue in the musescore.org thread below, and keep this issue on topic.
