A couple of options. Do you want the solution to be portable so that you can run on different computers, or do you want you to carry the portable package to the end?
You can use package configurations for both. They are available in the SSIS / Configurations menu. You specify the properties of the objects you want to make dynamic, and this is saved in the XML file (for example, connection strings, path locations, variable values).
You can change this xml file in a text editor, and when the package is launched, it will use these values. However, if you work on multiple machines, this is still a little ridiculous. You may need to re-specify which configuration file to use when opening the solution on a new PC.
Instead, if these are DB connection strings, look at using trusted connections. They mean that you do not need to enter SQL credentials. If this is a place for files, this will not work, but you can replicate directory structures or something like that.
