Hi @Austin31684 ,
Thanks for your feedback. If you want to capture the images, text or table together into a "Multiple Lines of Text" type column, I afraid that there is no way to achieve your needs in PowerApps currently.
If you would like this feature to be added in PowerApps, please consider submit an idea to PowerApps Ideas Forum:

As an alternative solution, you could consider take a try with the alternative solution I provided above -- add a individual "Multiple Lines of Text" column to store the image data captured from your canvas app. e.g. If you add a "Add Picture" control in your canvas app to capture the Image, you need to use JSON function convert the captured image into a base64 encoded data:
Set the OnChange property of the AddMediaButton1 to following:
Set(ImageData, Substitute(JSON(UploadedImage1.Image, JSONFormat.IncludeBinaryData), """",""))
then when you attach a picture through the "Add Picture" control, the base64 encoded data of the captured image would be saved into the ImageData variable. Then you could patch base64 encoded data of image to your SP List through the ImageData variable.
Please check and see if the thread solution I provided above could help in your scenario. If the solution I provided above is helpful in your scenario, please consider go ahead to click "Accept as Solution" to identify my reply as helpful.
