Please add a way to specify the location of multiple bits of text using container coordinates

I have an application where I need to put one text string (the Y-axis label) in the top left corner and a second text string containing source information in the bottom left corner. Placing text at the left edge of the graph seems to require specifying container X-coordinate 0. Title obviously supports creating one such label in container coordinates, but only appears to support one piece of text. https://plotly.com/python/reference/layout/ add_annotation supports multiple pieces of text, but does not appear to support container coordinates. https://plotly.com/python/text-and-annotations/#positioning-text-annotations-absolutely

Please offer one tool that supports both multiple strings and container coordinates if it is not already possible to do so. If it is possible, please clarify the documentation. If this is a good Plotly codebase contribution 0 for a data scientist, let me know -- I can attempt it.

Thanks!

从链接的布局参考和 add_annotation 定位文档开始，比较对多个文本字符串和容器坐标的支持。完成意味着要么记录一个同时满足这两个要求的现有工作流，要么定义并实现一种受支持的方式来组合它们，并通过项目的测试验证其行为。
