I do pretty much the same as you indicate. I do it as a multi-step process.

First I draw the groove, then I add the weld beads showing the joint penetration and depth of fusion. They are nothing more than a representation of what is required for most projects. The number of beads and the size of the beads may vary from joint to joint, so the sketch is nothing more than an idealized representation of what the welder will do.

Once all the beads are drawn, I use the cut function to remove the weld face of the initial bead. The weld face is remelted by successive weld beads, so this representation is more accurately represent what one would see if the groove was cut and macroetched. I do not represent the HAZ of each weld bead unless I am actually trying to show metallurgical features for a classroom presentation.

The size of the weld beads are dependent on the thickness of the joint and the diameter of the electrode used. Since you have a good number of years as a welder under your belt, you should have a pretty fair idea of the size of the weld bead that can be deposited in various welding positions. That is an advantage of someone with experience under the hood compare to someone that never struck an arc. You have a leg up on your completion my friend.
