Colors for Vowels

Hello,

I just created this in PowerPoint, but would rather continue in H5P. LMK if there is a tool to do the following, as I describe my PowerPoint:

1. The slide contains 12 text placeholders. The first is at the top. The next 8 are all small and aligned at the bottom of the slide.
2. In placeholder 1 I type an entire word: HEAPING
   In placeholder 2, I type a single letter: H
   In placeholder 3, I type a single letter: E
   In placeholder 4, I type a single letter: A
   In placeholder 5, I type a single letter: P
   In placeholder 6, I type a single letter: I
   In placeholder 7, I type a single letter: N
   In placeholder 8, I type a single letter: G
3. I delete the remaining placeholders, since I won't use them for this word.
4. Since the objective is to help learner identify vowels, I begin with first vowel and click placeholder 3. I add an animation (type=Emphasis/Font Color), choose a bright color, and associate the animation with the specific placeholder. I repeat the process at placeholders 3 & 6.
5. Now that the PowerPoint is ready, you start a slideshow. Slide 1 shows HEAPING spelled twice. Once at the top of the page (just for show), and again at the bottom, each letter in an individual placeholder, which looks a little wonky, spacing-wise. I ask the student to identify vowels. The student says H, I say no. Student says E, I say 'very good' and I click the individual E. Its color changes from black to the bright color. And so on...

Thank you for your advice. I love H5P and prefer to use it, if I can. Moreover, I am experienced with PowerPoint, but it took WAY too long to create 8 little slides this evening. It's not the right tool for the job.
